Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the configuration of an in-building lighting control system using an electronic exchange.

(Prior Art) Conventionally, as a reference document of technology in this field, there is one disclosed in "Japanese Patent Publication No. 56-42037", for example.

Generally, lighting equipment in office buildings is installed on the ceiling, and the lighting equipment is turned on and off by pulling a cord attached to the lighting equipment or by turning on and off a control switch installed on the wall. I was worried.

(Problems to be solved by the invention) However, in either case, there is a drawback that the lighting can only be controlled at the location where the cord or switch is installed, and the wall switch method requires indoor wiring to be routed to the wall switch. .

Therefore, in large buildings, installation and wiring of piping and switches for indoor wiring requires a large amount of cost and man-hours.

(Means for Solving the Problems) The present invention has been made to solve these problems, namely, to eliminate the switch from the wall and to eliminate the need for indoor wiring to the switch. This is a lighting control system in which the blinking of equipment is controlled by push buttons on a multi-function telephone connected via an electronic exchange installed in an office.

(Operation) In the present invention, a private branch exchange converts a control dial from a multi-function telephone into a control code, and then sends it to the main controller using an empty line of a transmission line consisting of a plurality of lines. The main controller analyzes the control code, identifies the lighting device to be controlled, and controls the lighting device using a relay board, thereby eliminating the above problem.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention.
In the figure, 1 is a multifunction telephone, 2 is an electronic exchange, 3 is an interface circuit between the electronic exchange 2 and the main controller 4, 5 is a sub-controller, 6 is a relay board, and 7 is a lighting device. However, 7 does not mean one lighting light, but a group of lighting lights that are always turned on and off at the same time due to indoor wiring.

A large number of multifunction telephones 1 are installed in an office to facilitate lighting control, and the interface circuit 3 statistically calculates the number required to simultaneously transmit and receive lighting control signals. The sub-controller 5 is installed on each floor or within an area divided into fire prevention areas, etc., and there are no more than 10 lighting devices, which is called a zone. The same number of relay boards 6 and lighting devices 7 as sub-controllers 5 are installed.

Although multiple feature phones can be installed within one zone, a feature phone can only control lighting equipment within its own zone. That is,
A single multi-function phone can control up to 10 lighting devices.

In FIG. 1, it is assumed that the multifunction telephone 1-1 and the lighting devices 7-10 to 7-19 are in the same zone.

FIG. 2 is a diagram showing the correspondence between zones and lighting equipment.

The multi-function telephone 1 is provided with push buttons for lighting control, and each push button is preset with a 3- to 5-digit code for lighting control and a combination code for control devices (hereinafter referred to as
control dial).

Since the contents of this control dial are the same for all multifunction telephones 1, it is not possible to identify the lighting equipment to be controlled by the control dial. The electronic exchange 2 uses the control dial and the calling class information (the zone number is included in the class information) of the multifunction telephone 1.
Convert to control code. The control code consists of 2-digit floor information, 1-digit zone information, and the required number of lighting equipment numbers (up to 10) to be controlled.
Keywords for preventing tampering can be added as necessary. FIG. 3 shows an example of the structure of the control code.

Figure 4 shows the push button numbers (corresponding to the control dial)
This shows examples of combinations of numbers for lighting equipment to be controlled. For example, the lighting equipment controlled by push button 1 is "0" and "1", and a maximum of 10 lighting equipment can be controlled by one push button. can be controlled in any predetermined combination.

In addition, in this example, since the control code does not include a control signal for turning on or off the lighting equipment, the system is designed to turn off the lighting equipment that is ON and turn on the lighting equipment that is OFF. I am building a multi-function phone, but I added a push button to the multi-function phone and turned it on.
Alternatively, adding OFF information is easy as a system upgrade of this embodiment.

Next, an outline of the operation in this embodiment will be explained.

After taking the multi-function telephone 1-1 off-hook and hearing the dial tone from the electronic exchange 2, when one of the push buttons for lighting control is pressed, the pre-registered control dial is sent to the electronic exchange 2 as a PB signal. Ru.
The electronic exchange 2 converts the control dial received from the multifunction telephone 1 into a control code as described above, selects one of the available interfaces 3, activates the main controller 4, and then transmits the control signal. Send as PB signal. Since the main controller 4 may receive control codes from a plurality of interfaces 3, it determines the order in which each control code is sent and sequentially sends them to the sub-controllers 5-1 to 5-r. The sub-controllers 5-1 to 5-r are multi-drop connected to the same transmission line, and the signal transmission method from the main controller 4 can be realized using known technology (for example, Japanese Patent Publication No. 56-42037), so a detailed explanation will be omitted. Omitted. Further, each of the sub-controllers 5-1 to 5-r extracts floor information and zone information from the control code received from the main controller 4, and determines whether it is in its own zone.
In the case of another zone, the control code is discarded, and in the case of the own zone, the lighting device to be controlled is extracted from the control signal, and the switch corresponding to the corresponding lighting device on the relay board 6 is driven. When the switch is driven, the relay contact of the relay board 6-1 as shown in FIG. 5 changes from ON to OFF or from OFF to ON, and the lighting equipment turns on or off.

From the above explanation, if the building size is small,
It is possible to reduce the number of interfaces 3 to one, and when the number of sub-controllers 5 is one, it is also possible to configure the main controller 4 and sub-controller 5 as a set of controllers. .

(Effects of the Invention) As explained above, according to the present invention, in order to make it possible to turn on/off lighting equipment from the nearest telephone, wall switches are eliminated from inside buildings and offices, and the piping to the switch is - Eliminates the need for wiring. Therefore, there is an economic effect on the architecture of the building. In addition, when changing the combination of a switch and lighting equipment, conventionally it was necessary to change the indoor wiring, but with this invention, changes can be easily made by simply changing the data in the electronic exchange. .

This point will have a significant effect in the future, considering that in tenant buildings, interior partitions often change due to tenant changes. In addition, in daily life, there is no need to go to the switch on the wall in the morning and evening, which reduces one of the chores for building residents.
It will have a psychological effect. In addition, since the main controller unit can monitor all lighting conditions in the entire building,
This also has the advantage of making building management easier.
